Eriugenas negative Ontologie

Recently, there has been an upsurge of interest in the work Periphyseon of the early medieval philosopher John Scot Eriugena. Previous research has classified the book either as a piece of Neoplatonic philosophy or as part of the Latin dialectic tradition, which has led to one-sided interpretations. The present publication focuses instead on the philosophical claims defended in the Periphyseon itself, examines its originality and discusses the soundness of its argumentation. As a result, a hitherto unnoticed basic thought of the work has been uncovered, namely the concept of a negative ontolog.
